I To @ZZ- weom t may concert:

Beit known that I, NORMAN MAiasHALL, of

Newton, in the countyo Middlesex and State of Massachusetts, have invented certain new vzo ad'-usefl1l Improvements in Machines for S ap ing' Tubular Articles, of=which the fol-l lowing is a specification.

The invention relates to a machine for shaping tubular articles, such; as insulatinglinings for incandescent-lamp sockets, 1n

which the article is shaped by the action of d ies consisting of a die-post corresponding slze and'shape tothe interior of thearticle to be formed and a die-sleeve corresponding sizeand shape tothe exterior of said'article.

' In 4the machine embodying the .various features of the invention the blanks from which the articles are to be made are presented to one of. the dies and by it are carried into position'to be operated on by the cooperating; I` die and are tnen carried into position fto be I acted upon by an ejector mechanism, which l `removes the article from the-die and dischargesiti'rom the machine. y

To enablethe different operations `performed on each blank to be performed concurrently on different blanks, thereby increasing the capacity of the machine, a'series "of dies may be, and preferably-are, mounted upon a carrier which brings each-die into po-.' sition to receive the blank, then into position' to coperate with the other` die, and then into position to coperate witn the ejectorl mechanism.

ried by either the die-post or the die-sleeve,- and in case the machine '1s provided with a series 'of dies each of which coperates with a single die the series mayconsist either of dieosts or die-sleeves, the cooperating mechanisms being correspondingly modied.

In the drawings, in lwhich "a machine is shown 'embodying the features of'the inve'n tion in the preferred forms, Figure 11s a iront elevation of the machine. Fig. 2 is a side elevation looking toward the right, Fig. 1. Fig. 3 is a central vertical section. Fig. 4 is ay orizontalsection von the line 4 4, Fig. 1. Fig. 5 is an enlarged detail of the extractor mechanism. A 1

Themachine'shown isintended for shaping `the insulating-linings for. incandescentlamp sockets, which arel provided with end portions of different diameters, vand the die post and die-sleeve, which coperate in shapmg the linings, are of a--orm to give'the blankl The blanks may be presented to and car.-`

forr'n'.' The machine is provlded with aseries of die-posts A, mounted upon a carryingplate B, 'mounted to rotate about a stud C kandfsupported upon the bed-plate `D of the machine'. 'q The A carrier-disk' B is provided on its' periphery. with a series of ratchet-teeth correspondingv number to thenumberLof die-posts onthe carrier, and the carrier is 1ntermittently advanced by a pawl b, pivoted to' the end of a slide b and held in engagementwith the ratchet-teeth by a spring b2. The slide b is reciprocatedby means oi a cam b3', secured tothe ,driving-shaft E and engaging the end of a lever b, connected with the slide by means of a link b5 and held in engagement with the cam by al springt.

By the-rotation of the carrier B the die- `posts A are brought successively into positionbeneath a die-sleeve F, which is secured toa cross-head F', mounted upon vertical guideways F2 and reciprocated by a-crank F3 on the driving-shaft, which isiconnected with the cross-head by "a rod F4. yOn the downward stroke ofthe die-sleeve F this4 sleeve cooperates With the die-post A, which is in position beneath it to shape the blank carried by'v the die-post, and on the upwardstroke of the die-sleeve the shaped `blank is stripped from the die-sleeve bythe stripping-post G, which extends through the die-sleeve above the blank lon ,thev die-post and prevents the upthe frame oithe'machine.y l

The rotation of the carrier Balso brings theI shaped blanks from the die-posts and discharge them'` fromthe machine. This errtractormechanism consists of three fingers H, pivoted in 'a bracket H', secured to the cross-head F andl provided with hooks H2 vfor,engaging the lowerend ofthe blank.` Two i from theilining is: `sh aped the desired .Ward movementlof the blankvith the diel, sleeve. The strippingpost 1s secured 1n A'fixedposition in a cross-bar G', secured to of the fingers H are drawn toward each other by a spring-H3, and the other finger is pressed forward by a leaf-,spring H4. The lower ends -of the'nge'rs are inclined outwardl so that as the cross-head descends the inc ed surfaces on the ends of the ngers will ride over the end of theblank, thereby spreadingv the lingers 'against the tension of lthe springs. When-the'hooks H2 have passed below t e lower end ofthe' blank, the springs will draW the iinffers inward into the slots A2 in the posts A, so that on the upward stroke of the crosshead F the hooks will engage the lower end of the blank and draw the blank off of the die-- post. As the cross-head approaches its upper position the blank carrie by the ejector- `ngers. is discharged from between said iingers by a discharger 1,-pivoted in the bracket H and provided with an operating-arm I', which strikes a stationary cani I2, secured-to the frame'of the machine. is held normally in a position where it will not strike'tlie blank by means of a spring I3.

The blanks from which the linings are to be 'shaped are placed by the operator upon the 4die-posts Aas they come intoposition at the front offthe machine, and in case the blanks are not forced onto the posts far enough to i engage the shoulders A/they will be'forced positionA beneath' the cross-head of a block J, blanks and ffneath the die-sleeve and stripper-post, where #the die-post and discharged from the ma,

the articles,

it is acted upon by the dies and retained upon the die-post by the action of the stripper-post and then is carried into position beneath the ejector mechanism, where it is removed'froin chine.

What I claim, and desire ters Patent, is-

1. A machine for shaping tubular articles having in combination a die-post and a diesleeve for shaping the article, an ejector mechanism, and means Afor moving one of said 'die members into position to receive the blank, then into position to cooperate with the otherdie member and then into position to cooperate with the ejector mec anism, substantial] -as described.

2. A mac e for shaping tubular articles having in combination a traveling dieepost, a. die-sleeve for cooperating therewith to she ne an ejector mechanism, and means for moving the dic-post into osition to cooperate with the die-sleeve and t en into position to cooperate with the e'ector mech` anism7 substantially as describe 3. A machine for shaping tubular articles having in combination, a carrier, a series of to secure by Let- Idie members on said carrier, a die member to Thedischarger I' which the die members on thecarrier are suc-- to which the posts are successively presented by the carrier, and an ejector mechanism to which the substantial y as described.

6. A m"'hine for shaping tubular articles having inconibination, a carrier, a* series of vdie-posts thereon, a reciprocating die-sleeve,

a fixed stripper-post extending through said sleeve, and an ejector mechanism, substantially as described.
